I am not sure whether it is the same thing. Maybe it was inspired? Here
is the source [1] and the documentation [2].

It is in the development version of LuaXML [3].  Documentation is only
in the source comments at the moment, I am still working on it. There is
also CSS selector library [4], which can be used for element traversing
and matching, using CSS selector syntax. I plan to use it for
conversions from XML to LaTeX, or other formats (StarMath?).  But it is
not usable yet.  Anyway, the usage can be seen in the unit tests ([5],
[6]).
